These offer similar specs (30V, -4.3A, low RDS(on)). Verify pinout and parameters for exact compatibility.

Features

The AO3401 is a P-channel MOSFET with the following key features:
- Voltage Rating: -30V drain-to-source (V_DS).
- Current Rating: -4.3A continuous drain current (I_D).
- Low On-Resistance: 40mΩ (max) at V_GS = -10V.
- Gate Threshold: -1V to -2.5V (V_GS(th)).
- Fast Switching: Low gate charge (Q_g) and output capacitance (C_oss).
- Package: SOT-23 (compact surface-mount).
- Applications: Power management, load switching, battery protection.
Ideal for low-voltage, high-efficiency circuits.

Manufacturer

The AO3401 is manufactured by Alpha & Omega Semiconductor (AOS), a U.S.-based company specializing in power semiconductors. Founded in 2000 and headquartered in Silicon Valley, AOS designs and produces MOSFETs, power ICs, and other components for applications like consumer electronics, computing, and industrial systems. The AO3401 is a P-channel MOSFET commonly used in power management circuits. AOS is known for its innovation in power efficiency and compact packaging.

Application

The AO3401 is a P-channel MOSFET commonly used in:
1. Power Management – Switching and load control in portable devices.
2. Battery Protection – Reverse polarity and discharge prevention.
3. DC-DC Converters – Efficient voltage regulation.
4. Load Switching – On/Off control in circuits.
5. Consumer Electronics – Smartphones, tablets, and wearables.
6. Automotive Systems – Low-power auxiliary circuits.
Its low on-resistance (RDS(on)) and compact SOT-23 package make it ideal for space-constrained, energy-efficient applications.

Package

The AO3401 is a P-channel MOSFET typically available in a SOT-23 surface-mount package (3-pin). This compact package is widely used for low-power applications due to its small size (approx. 2.9mm x 1.3mm) and ease of soldering. Other variants may include SOT-23-3L or similar designations, but SOT-23 is the most common.
